## Description

Karn, Legacy Reforged is a standout Mythic Rare artifact from the 2023 Magic: The Gathering expansion March of the Machine: The Aftermath. As a Legendary Artifact Creature — Golem with a mana cost of five, this card is numbered 99 in the set and features a premium foil finish that enhances its appeal for collectors seeking high-rarity pieces. The artwork by Daren Bader brings this iconic planeswalker back in a new form, making it a focal point for those completing the MAT set or building artifact-focused collections. In gameplay, Karn’s power and toughness are determined by the largest mana value among artifacts you control, scaling dynamically with your board state. During your upkeep, the card generates colorless mana equal to the number of artifacts you control, with a unique restriction preventing the use of this mana to cast nonartifact spells. Crucially, this mana does not empty at the end of steps or phases, allowing for flexible resource management. This mechanical design makes it a valuable addition to decks centered around artifact synergy. For collectors, the combination of the Mythic Rare status, the foil treatment, and the character’s legacy within the Magic: The Gathering lore creates a compelling item. Whether you are investing in rare artifacts or expanding your library of legendary creatures, this card represents a significant piece of modern TCG history.
